The anthocyanin on the inner side of the corolla of ‘SOLHY016' ranges between a medium to strong and strong intensity while that of ‘Belmonda' ranges between a weak and a weak to medium intensity. The anthocyanin colouration on the inner side of the corolla of ‘SOLHY016' has a high proportion of blue while the anthocyanin colouration on the inner side of the corolla of ‘Belmonda' ranges between an absent or very low and low proportion of blue and that of ‘SOLHY016' has a medium proportion of blue.

Origin & Breeding History: 'SOLHY016' (experimental designation 21HY5480) is a true hybrid potato originating from the cross between the female parent ‘PL0229' and the male parent ‘PL0238' conducted at the Agventure B.V. breeding station in Ressen, The Netherlands in 2021. Based on maturity, plant structure, tuber characteristics as well as disease resistance the resulting progeny was designated 21HY5480 in 2022. Hybrid seed production commenced in 2022.

Tests & Trials: The comparative trials for 'SOLHY016' were conducted in Sainte-Croix, Quebec during the 2023 and 2024 growing seasons. Seeds were germinated in a green house and after 4 weeks the plantlets were transferred to an outdoor canopy for 5 days for acclimatization. The plantlets were then transplanted in the field and irrigated daily for 2 weeks. The field trial consisted of 4 replicates with plots arranged in a RCB Design. Each plot was a 5-metre-long hilled row containing 25 plants spaced 20 cm apart. Rows were spaced 0.915 metres apart. Lightsprout characteristics were assessed on 20 tubers harvested from the comparative trial and observed approximately 3 months after storage at 4 degrees Celsius.
